Description
The DS2154 Enhanced Single-Chip Transceiver (ESCT) contains all of the necessary functions for connection to E1 lines.
The device is an upward compatible version of the DS2153 Single-Chip Transceiver.
The onboard clock/data recovery circuitry coverts the AMI/HDB3 E1 waveforms to a NRZ serial stream.
Features
- Complete E1(CEPT) PCM-30/ISDN-PRI transceiver functionality Onboard long- and short-haul line interface for clock/data recovery and waveshaping 32-bit or 128-bit crystal-less jitter attenuator Generates line build outs for both 120Ω=and 75Ω=lines Frames to FAS, CAS, and CRC4 formats Dual onboard two-frame elastic store slip buffers that can connect to asynchronous backplanes up to 8.192 MHz 8-bit parallel control port that can be used directly on either multiplexed or non-multiplexed buses Extra.
